LMX2592RHAT

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2592RHAT is a wideband frequency synthesizer with an integrated voltage-controlled oscillator (VCO) manufactured by Texas Instruments. It operates within a frequency range of 10 MHz to 9.8 GHz and supports input frequencies from 5 MHz to 1.4 GHz. The device functions on a supply voltage between 3.15 V and 3.45 V, typically at 3.3 V, with a working current of 340 mA. It utilizes Silicon technology and is housed in a 40-pin VQFN package suitable for surface mount installation. The component is rated for operation between -40°C and +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix RHAT against the datasheet to confirm the tape and reel packaging configuration. Ensure the ordering part number matches the exact pinout and thermal pad requirements for the target PCB layout. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a wide output frequency range up to 9.8 GHz is required without external VCOs. Consider the 340 mA operating current for power budget calculations. Evaluate the VQFN-40 package dimensions against available board space constraints. Compare performance metrics against the LMX2594 if higher frequency coverage beyond 9.8 GHz is necessary.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The LMX2592 belongs to the LMX259x family of wideband PLLatinum RF synthesizers from Texas Instruments. This series includes variants such as the LMX2594 and LMX2595, which offer extended frequency ranges up to 15 GHz and 19 GHz respectively. All members share similar architectural features but differ in maximum operational frequency limits.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The LMX2594RHAR or LMX2594RHAT may serve as substitutes if higher frequency support up to 15 GHz is acceptable. Verify register compatibility and pinout alignment before replacement. The LMX2582 offers similar functionality but lacks the integrated VCO.
